A bicycle disc brake rotor is provided with a base rotor plate and a surface region. The base rotor plate includes an outer portion that is formed of iron. The outer portion has first and second base surfaces facing in opposite axial directions. The surface region is formed by a diffusion process on the base rotor plate. The surface region has a corrosion resistant characteristic which is superior to the base rotor plate.

A disc brake caliper is basically provided with a caliper housing, a brake pad and an intermediate member. The caliper housing defines a slot that is configured to receive a brake rotor. The caliper housing is made of a first material. The brake pad includes a mounting plate. The brake pad is disposed in the slot. The intermediate member is disposed between the caliper housing and the brake pad. The intermediate member is made of a second material having a thermal conductivity that is smaller than a thermal conductivity of the first material.

A bicycle sprocket comprises a first member and a second member. The first member comprises a plurality of first teeth and a first body. The first body includes a plurality of first arms arranged in a circumferential direction of the bicycle sprocket. The second member comprises a plurality of second teeth and a second body. The second body includes a plurality of second arms arranged in the circumferential direction. The second member is configured to be attached to the first member so that an interior cavity is provided between the first member and the second member. The interior cavity is at least partially provided between at least one of the first arms and at least one of the second arms facing the at least one of the first arms in a state where the second member is attached to the first member.

A bicycle sprocket includes a sprocket body, and a plurality of sprocket teeth. At least one of the sprocket teeth includes a first layered member, a second layered member and a third layered member. The first layered member has a first axial surface and a second axial surface. The second layered member is attached to the first axial surface such that the first and second layered members overlap each other in an axial direction as viewed parallel to a rotational axis of the sprocket body. The third layered member is attached to the second axial surface such that the first and third layered members overlap each other in the axial direction as viewed parallel to the rotational axis of the sprocket body. The first layered member has a specific gravity that is less than those of the second layered member and the third layered member.

A disc brake rotor apparatus includes an annular inner member for mounting to a hub, an annular outer member concentric with the annular inner member and having opposite braking surfaces, a first intermediate member extending radially outwardly from the annular inner member to the annular outer member, and a second intermediate member extending radially outwardly from the annular inner member to the annular outer member. The first intermediate member is at least partially and axially spaced apart from the second intermediate member and forms a chamber therebetween.

Disk brake rotor with hollow portions

A bicycle disc brake rotor basically has a base rotor plate and a first thermally sprayed layer. The base rotor plate includes an outer portion having first and second base surfaces facing in opposite axial directions. The first thermally sprayed layer is laminated on the first base surface of the outer portion of the base rotor plate to form a first outer surface.

A bicycle disc brake rotor is provided that has a center rotational axis, and basically includes an outer portion and a cooling fin. The outer portion includes a first braking part defining a first braking surface and a second braking part defining a second braking surface. The first and second braking surfaces face in opposite axial directions. The cooling fin includes an inner portion radially offset from the first and second braking surfaces. The cooling fin further includes an attachment portion extending outwardly from the inner portion and sandwiched between the first and second braking parts. The first and second braking parts are separate and distinct individual parts from each other and from the cooling fin.

A bicycle disc brake rotor, having a rotational center axis, comprises a base portion including iron and a surface portion including iron, aluminum, and chrome. The surface portion is formed on an external surface of the base portion. A concentration gradient of chrome of the surface portion is formed in an axial direction parallel to the rotational center axis.
